This invention relates to devices for extracting the juice from citrus or other fruits, especially oranges. y It has for its general 7object to providea simple, convenient, effective and inexpensive device` vfor that purpose, adapted to both domestic yand counter use, the device being so constructed as to be easily cleaned orl sterilized. Y j

A special object of the invention is to provide a `juice extractor which, whil-e permitting the free dischargeof juice throughl the passageprovided therefor, will minimize leakage .betweenthe rind of the fruit and the extractor, and willV also prevent entrance of seeds and fiber into the discharge passage.

The extractor is preferably formed of two readily separable partsfthat are ,held together while in use,'by friction only.

Other objects and advantages of the inven-v t tion will be evident from the following Ade- Fig. 1;

scription of a preferred embodiment thereof,

reference being had to ,the accompanying drawing in whichi Fig. 1 is a perspective view of the device; Fig. 2 is a similar view with the two vparts separated;

Fig. 5 is a similar view, inverted, showing the device completely inserted; and a .A i l,

Fig. 6 is a cross section on line 6 6, Fig. 5, showing part of the interior of an orange.

. In the vembodiment of the .inventionillus trated in the drawing, theextractor is composed of two parts, which inv use are fitted together to form a unitary device, as shown in Fig. lr; said parts beingpreferably h'eld'together by friction only so that Vthey maybe readily. separatedV as shownin Fig. 2, for` cleaning or sterilizing. Figs. and 2 vshow the device in the4 position it occupieswhenthe juice of a fruit is being extracted.

The upper member in `those figures', which may be appropriately termed the coring member or penetrating portion, consists of a 'I main body part tubular in shape of Vapproximately uniform diameter .throughout having showing thejdevice partly 'inserted in ank atitslower end a shallow cup-like part or cup portion of considerably larger diameter. The tubular body part comprises two rings" 8, 8a,one at each end, connected together by narrowV strips 14,' with/long and wide aperjust sufficient to give the necessary strength .and rigidity to the body part. Because vof the size of these apertures l2A the juice of the fruit` has a maximum area-of access to the.

interior," of the tube, yor invotherwords, it`

turesl2 between, the width of strips 14 beingmi encounters minimum resistance in Ventering Y -thesameg Moreover, the construction; is in this respect simpler and hence less expensive than that of extractors having a large number ofrelatively small apertures. The object of the constructiony lastreferred to is .to

preventgadmission to the discharge passage of seeds and fiber or pith. That lobject is attamed otherwiseaccor ding tothe present invention, as presentlyexplained, thu'sr'naking .'ber is'integral with, or is permanently attached to, the ring 8a, ofthe tubularpar't. -Its upper :surface is slightly dished or .concaved.; to conform somewhat to the contour of an orange, and there are perforations 10, disposed ina circular row at the lowest Dart of the dished surface. through which juice can flow into the discharge'passage.

-i The lower member of the device, which may be termed the discharge member for spout portion, has a frusto-conical orfunnel-shaped body 15V andV a vertical ,annular flange 16 at the wide end thereof, said flange being of such diameter as to make a liquid-tight joint with the vertical annular lportion 13 ofthe coring member, which it encirclesv when the two members areffitted together. i l j `While it is preferable to form the device of'. two separable partait is obvious that the main advantages yof theinvention would be realizedv in a device whereinthe twoparts were permanentlyattached toeach other.

i I Inusing the device, say to extract the juicei" fus *las

of an orange as indicated at 19 (Figs. 4, 5, 6) the cutting edge l1 is forced through the skin or rind along the line of the axis of the fruit (Fig. 4). lVhen the coring member is in serted to its full length in the orange, as shown in Fig. 5, the walls of all the sections thereof, whose edges unite at the axis of the fruit, will have been severed and the juice- Acontaining cells-will be in free communica.

tion with the interior ofV tube 8, 8a, through the large apertures 12. The device, together with the orange, being now inverted, so as to occupy the position shown in Fig. 5, the dished part 9 of the coring member 'will be in Contact with the spherical surface of the fruit,

Yso as to assist in the compression whereby the juice is extracted.

. The disk of rind or peel severed from the body thereof will at this time occupy the position relative to the coring member shown in Fig. 5; that is to say, it will lie Within the ring 8a. Thus it will act as a stop or fender to prevent passage of seeds or pith into the discharge member, while kallowing sufficient space between its edge and the inner wall of j tube 8a for the juice to flow into the discharge dimensions, actual and relative, being obviously variable. It has been found that, for an extractor intended for use with oranges, the following dimensions are effective :length `over all, 2% inches; maximum diameter f( middle portion of device) 11,/2 inches; internal diameter of tube 3A inch.

It is obvious th-atmodifications, other than those indica-ted above, may be madein details of construction of the device without departing froml the spirit and scope of the invention as set forth in the vappended claims.

What is claimed is:

l. A fruit juice extractor, comprising a coring member having al tubular penetrating portion provided at one end with ya circular cutting edge and at its other end with a supporting portion of larger diameter than said penetrating portion; and a discharge member attached tosaid coring member, said discharge member' being of larger diameter where it joins the supportingportion of said coring member than the penetrating portion thereof; said penetrating portion being of approximately uniform throughout, so that when itis fully inserted in the vfruit the disk severed thereby from the skin or rind serves as a stop or fender betion and conducted vinterior Y diameter l remain on the outside of the fruit when said penetrating .portion is insertedin the fruit; said penetrating Vportion being of approximately uniform interior diameter, whereby it forms and passes into the fruit through an approximately annular opening in the youter surface thereof; said cup portion being formed to surround the opening made in 'the fruit by the penetrating portion and being in communication with the interior of said fspout portion, so that juice escaping from the fruit around the exterior of said penetrating portion is caught by the cup porthereby into the spout portion.
